Hysteresis
: sets a hysteresis (from 0% to 5%) for the upper thresholds. This
helps avoiding continuous speed changes in case the ICS keeps moving
around one of the threshold values.
SPEED CONTROL OBJECTS (MANUAL MODE)
Regarding the Manual Mode, the integrator must select the type(s) of the
communication object(s) that will permit commuting the fan speed:
Individual Control (1 Bit)
, which enables one binary object (“
[FCV1] Manual
Fan: Speed X
”) per fan speed. This object will activate the corresponding
speed on the reception of the value “1”.
Enumeration Control (1 byte)
, which enables a one-byte object (“
[FCV1]
Manual Fan: Percentage Control
”) that will switch the fan speed upon the
arrival of the proper integer value (0, 1, 2, 3, 4).
Note
:
to prevent damage to the installation, under the manual fan control,
speed 0 (fan off) will not be available while the valve is open
.
Percentage Control (1 Byte)
, which enables a one-byte object (“
[FCV1]
Manual Fan: Percentage Control
”) that will switch the fan speed upon the
arrival of the proper percentage value according to the KNX standard (see
Table 4).
Step Control (1 Bit)
, which enables a one-bit object (“
[FCV1] Manual Fan:
Step Control
”) for increasing (value “1”) or decreasing (value “0”) the current
speed level sequentially. This sequence can be either
cyclical
(a further step
once reaching the maximum level activates the minimum level again) or not.
